That's cool, but 32 mpg is still more than even the EPA estimate, which is always higher than true mileage. Exactly what kind of "city" driving are you doing? I'm thinking maybe it's not as "city" as my "city" driving. I probably spend as much time idling as I do driving due to traffic and excessively frequent stop lights[:@]

Still, if I drive gently I can get 1 mpg below EPA in the city, so I don't consider that awful. I'm just jealous of your seemingly insane MPGs!

 

yea, id really like to know why i get somewhat poopy mileage, I got quite a few mods, if anything, I should be getting better, due to the motor running leaner.

 

I get about 26 in the city with mine and I was a bit bummed about that too. I guess that it is because I only drive about 5 miles to work everyday. Need to get it out on the interstate and let it run.

 

could the s. plugs or pcv have anything to do with it?

 

Well, the city i live in is fairly large, but not quite like what you're describing. I have probably 8-12 stop lights on my way home from work (and TO work obviously) depending on which way i go. And i never have to sit through more than one set of cars at a given light, so i'm not idling nearly as much as you are. I dunno, Next time i get a full tank i'll really keep an eye on it and try to give a precise number.

 

say 40 any numbers yet?

 

nope, cause i'm broke as a joke and haven't filled my tank completely in a long time. Soon tho, i swear.

 

I'm getting about 24-30mpg on my 7th gen EX. 60% local driving & 40% highway. My engine is still 100% stock.

Beside spark plugs, change your wires & distributor cap too. Replace the air filter or if you are using an aftermarket intake, clean the filter.

I just replaced my spark plugs & air filter last week. I noticed a better mpg this week so far. 18mpg for a Civic is extremely low.

 

I changed my spark plugs Friday afternoon. Haven't done the plug wires yet. Filter is new but it's a Bomz Air Filter. What is the #1 type of filter to get?

 

i get 33 mpg most of the time but that is about 70% hwy. when me and my girl park for 1.5-2 hrs on a hot day or cold night then its about 28 mpg.
